Screen Capture File Format
TinkerTool used to let you change the file format used when you did a screen capture (shift-command-3 or shift-command-4). At some point I used this to change the format to pdf. Now the option in TinkerTool is greyed out. (I don't know when this happened; with the upgrade to Jaguar I guess.) However, whenever I do a screen capture, it still ends up as pdf. How do I switch it back to tiff? Is there some other way to switch file formats?
